BELIZE PROJECT GALLERY
The broad spectrum of the Maheias United portfolio reflects our diverse capabilities and areas of expertise. We specialize in challenging projects, regardless of size or dollar amount, and we are continually expanding our in-house resources to address new challenges and opportunities.
Some of the more recent projects that we have worked on that reflect our diverse capabilities are:
MIDDLE SEX BRIDGE
Timber piles were driven for this project from the north and south embankment. The main contractor relied heavily on our expertise in pile installation to allow this project to finish 6 days ahead of schedule.
BELIZE AUDUBON SOCIETY – TIMBER MAIN AND FINGER DOCKS
Construction of this timber dock at Half-Moon Caye, located some 36 nautical miles southeast of Belize City, required precise coordination of materials, tools, equipment, crew and subsistence supplies to minimize barging and boating costs. Although this conservationist island had only the most basic necessities on site, our construction crew was able to adjust to this environment and complete the project as specified, on budget and on time.
US ARMY SOUTH ARMY CONTRACTING AGENCY
The Americas – New Horizons 2007 – Earthworks, Building Renovations
New Horizons 2007 was an expanded program to include the renovation of five existing buildings at the Price Barracks Housing area, upgrade of the base camp site to include lighting, plumbing and waste water management in addition to construction of four school buildings and latrines. Due to weather delays, the work execution period was cut by five weeks, which meant longer work days and weeks for the separate crews. Effective Project management of six departmental crews ranging from earth works to concrete supply crews enabled us to deliver top value service within an eight week period.
EPOXY FLOORS– HEALTH SECTOR REFORM PROJECT
Epoxy Floors – Health Sector Reform Project – Hospitals and Polyclinics
Where sanitary environments are a requirement as in Hospitals and clinics, seamless floor systems are preferred. Selby 700 Epoxy floor systems offer not only sanitary environments by effecting seamless floors, but have the added function of being able to withstand the continuous cleaning processes that is a part of these institutions. Because of these benefits, the Health Sector Reform Team chose this product to be installed in both the Corozal and Orange Walk Hospitals.
Epoxy and Polymeric Floors – Citrus Industry, Stann Creek Valley
Citric acid is highly corrosive and will deteriorate any un-treated concrete surface over time. The Citrus Factory at CPBL in the Stann Creek Citrus Valley had floors that had seen significant deterioration from citric and caustic acids used in cleaning. The management needed a long-term solution to the recurring problem. Our line of BASF concrete admixtures, construction products and flooring systems allowed us to put forward a proposal for removal of the existing slab, replacement of the slab using special hardeners in the mix design and installation and sealing of construction joints. The chemical and abrasion resistance sought was achieved using Selby 700 series epoxy floor coating for the general environment, while Ucrete tough floor offered extremely high chemical resistance in the fill rooms where the citric juices was the concern and where the floor is exposed to continual wet processes.
PILED PREFAB RETAINING WALL
Our piled pre-fab retaining wall has been installed along the coast as well as canals. The design features:
prestressed precast concrete piles installed at each 10’ center to center for the main wall and at each 20’ for tiebacks.
6” x 10’ x 10’ RCC Slabs - #4 steel @ 8” both directions
40” x 15” RCC Top Slab
All concrete designed at 5000-PSI minimum compressive strength at 28 days, using ASTM C-150 Cement and corrosion inhibitor admixture.
Prefab slabs are installed to a nominal depth of 8’ by mechanical means.
Concrete cover for all concrete is 3”.
Tie-back beams installed at every 20’
Optional decorative concrete top slab
REHABILITATION WORKS
Carlos Carranza Berm Repair and Restoration – APRIL 2010
Contract work on this project was in relation to the Tradewinds exercise. The works were prepatory and restoration works and included removal of existing material, re-shaping of berm and slope embankment to 1:1 in maximum layers of 20cm. Compaction was done in compliance of ASTM D 1557 for cohesive materials (90% compaction).
In addition, the firing positions at this K-D range were restored to original condition including the cmu walls. Finally, we provided for grassing of the reconstructed berm using local grass as a form of erosion control.
Albert & Regent Street Rehabilitation Works - 2009
Our involvement in the rehabilitation project of downtown Belize City included the demolition of all existing sidewalks on Albert Street and construction of drains and new sidewalks with an architectural finish. Stamped Concrete was chosen for its aesthetic value and the Maheias United decorative concrete team delivered on the concept. On Regent Street, drains were repaired and sidewalks were installed on both sides of the street. The result: a friendlier and safer walking environment for Belizeans and visitors alike.
CANTILEVERED RETAINING WALL –1200 LF
Sub-Contract work for this project involved the production of precast cantilever retaining wall elements at our precast plant in Belize. The prefabricated elements were transported via the Coastal Highway to the Big Creek Port for barging to the island. The cantilever retaining wall was designed by our in-house engineering department which includes a Structural and Civil Engineer. The design specified an internal stem of steel-reinforced concrete in the shape of an inverted T. Cantilever retaining walls are made of reinforced
Broad Spectrum Portfolio
concrete that consist of a thin stem and a base slab. In the design, having known the lateral earth pressure, the following considerations were made to check for stability:
Over-turning about its toe
Sliding failure along its base
Bearing capacity failure of the base
Having examined these parameters, each component of the structure is checked for adequate strength, and the steel reinforcement of each component was determined. Also, adequate drainage was provided by means of weep holes. This step was taken to minimize increases in lateral earth pressure due to saturation of backfill material as a result of rainfall. This type of wall used much less material than the traditional retaining wall and proved effective for the specific soil conditions of this project.
With the exception of barging all work was carried out using our in-house resources
DECORATIVE CONCRETE WORK
Stamped concrete, on the other hand, is integrated in the wet concrete process. While enhancing the elegance of your property, the stamped surface is also a protective part of design – resisting stains, cracking and fading, and able to withstand vehicular traffic.
Stamped concrete can be used for walkways, patios, entranceways and even residences; anywhere you wish to create that look of slate, brick or stone - its ability to resemble other building materials (such as flagstone, tile and brick) makes stamped concrete a cheaper, more durable and attractive alternative to those materials.
AGRIPINO CAWICH /YOUNG BAN BRIDGE PILING CONCRETE WORKS
As the sub-contractor for the piling works, we executed the installation of all 600mm diameter steel tubular piles for the pier and abutments of this 370 ft. long bridge, both vertical and raked. Included in the works was the welding of base stiffening cruciform to the tubular piles, and welding of the pile splices. At a later stage, we supplied this project with
high strength concrete for the bridge deck, which was pumped 390 ft. across the trusses due to access restrictions.
BENNY’S SUPERSTORE – FOUNDATION PILING
Arguably the tallest building in Belize City and perhaps the entire Country, the Benny’s Superstore project was a coveted project for which the supply of foundation piling and services was very competitive. Pre-qualification involved the investment to produce specially designed piles of 5/8” tendons with 6 strands. This required adjustment to the bulkhead of the self-stressing forms at our plant. We were able to meet all the stringent requirements of the project, including the installation of the piles by diesel hammer. The project required the installation of 380 prestressed piles of which our company was contracted to install 60% of the total amount including all the specialty piles.
CAVES BRANCH BRIDGE - PILING
Piling works for this project involved the production of shoe piles made to MOW specifications. Raked piles were installed from the river bed for the center support structure of the bridge. In addition, piles for the north and south abutments were installed. The job required crossing the equipment through 2 feet deep water and was accomplished during the dry season.
DECORATIVE CONCRETE WORK
Our decorative concrete projects are featured throughout the country of Belize including the Cayes. The decorative concrete options that we feature include colored and textured finishes achieved through acid staining, integral colors and concrete stamping. Through acid staining we are able to achieve variegated color shades on cured concrete in rich colors that resemble the look of natural stones and patinas.
HOPKINS HARBOR CONDOMINIUMS – FOUNDATION PILING
Piling works involved the manufacture of 275 no. 12” square pre-stressed concrete piles to specification. Piles were transported via flatbed to site in Hopkins Village, Stann Creek District.
Installation of the piles through dense soil required us to design driving criteria to adequately meet the load bearing required by the client. This necessitated the adjustment of the weight of the drop hammer which was effected through our in-house welding department. Due to the length of the piles, we created a set of box leads to 60 feet fixed to the boom to properly house the 45 foot piles as well as hammer. The job was scheduled for and completed in 6 weeks.
LAS TERRAZAS PH. I & II – FOUNDATION PILING AND SERVICES
Sub-contract piling works for this resort involved manufacturing of 395 no. reinforced concrete piles, barging of the manufactured piles to site some 6 miles north San Pedro, Ambergris Caye. In addition, crane and other required equipments were also transported by barge to site to carry-out installation of piles and pile-cutting. This involved coordinating proper and sufficient delivery of piles to site to keep the foundation works on track. Except for barging, all other core functions were performed in-house.
OVERPASS BRIDGES – ORANGE WALK
Piling works for this project involved sub-contract work the installation of pre-stressed concrete piles. Piles were driven according to the set driving criteria. Supervisors for the main contractor provided on-site supervision throughout the piling works.
RANCHO DOLORES BRIDGE - CONCRETE
Works for this bridge included the supply of concrete to the steel case piles. We were tasked with providing a solution for supplying concrete 300feet across the trusses and down to the steel case piles below.
4X4 CONCRETE – RUNWAY CHARLIE, PHILLIP GOLDSON INTERNATIONAL AIRPORT
Repairs to run-way Charlie required a supply of 4x4 concrete, which enabled overnight repairs to the damaged slabs. Our in-house capacity to design, test and deliver custom mixes put us at an advantage over other companies. A mixture of high-range water reducers, stabilizers and Accelerators along with our expertise at proportioning allowed the authorities to effect the repairs in approximately 19 hours, the period between the departure of the last flight on one day and the arrival of the first on the day following immediately. The mix design delivered a high-slump concrete that was easily handled and finished, yet met and exceeded strength requirements at 8000 psi in 12 hours.
T.V.E.T (TECHNICAL VOCATIONAL EDUCATION TRAINING) AND POLYCLINIC PROJECTS- CONCRETE, PLACEMENT AND QUALITY CONTROL
As the sub-contractor for concrete supply, we were tasked with supplying timely delivery and placement of high strength concrete to T.V.E.T locations countrywide. Our contract included the design of mixes for two classes of concrete, carrying out test mixes and field sampling during delivery. Due to time constraints, mobilization of equipment, materials and personnel as well as site preparation had to be done in a timely fashion on 24-hour notice. We met and exceeded expectations, saving the main contractor as much as 10% on overall job time.
TOURISM VILLAGE – CONCRETE FINGER DOCKS
As the main contractor for this project, we were responsible for all works including provision of marine piles, installation and cutting, production of pre-cast beams and slabs, installation and placement of 2” topping to slabs. Production of elements were done at our pre-cast plant and delivered to site by barge. Installation was done over water from the deck of a 100 ton barge. Except for barging, all aspects of construction were done using in-house resources.
US ARMY JOINT TASK FORCE PELICAN- NEW HORIZONS 2000-EARTHWORKS, CONCRETE AND CONCRETE BLOCKS
As the sub-contractor on this project, we were responsible for site-prep, lining out, filling and leveling of fill material, supply of concrete blocks including stretcher blocks, corner blocks, half corner blocks, Jamb blocks, half jamb blocks and U-style blocks, supply and placement of structural concrete, supply of all aggregates, sand and stone, and cement to sites. These sites were dispersed throughout the South-western part of the country from Valley of Peace on the Hummingbird Highway, Gales Point Manatee on the Coastal Highway to Hopkins Village off the Southern Highway. These sites included remote areas with only rudimentary access roads.
US ARMY TASK FORCE JAGUAR – NEW HORIZONS 2003 – DRAINAGE, ROAD BUILDING, CONCRETE
The main focus of the New Horizons 2003 project was installation of drainage for the Holy Ghost School compound, filling and leveling including compaction of the foundation sites and the supply and pumping of 10” slump concrete into walls for three prefabricated school buildings in the Stann Creek District. We were also tasked with clearing and road-building for the base camp.
US EMBASSY RESIDENCES – CONCRETE AND PUMPING
Concrete supply for this high-profile residential project was highly competitive, including not
only local, but regional suppliers. The contract for construction of all fifteen residences,
pools, tennis and basketball courts, club-house, roads and double-walled perimeter fencing
was scheduled for 12 months. Demand for high-performance concrete and timely delivery
could only be met by commitment of significant resources. To this end, our proposal to
invest in a fully-automated Dry Batch Type Johnson Ross Batch Plant with a production
capacity of 100 cubic yards per hour along with stringent quality control procedures in place
was tantamount in putting forward the winning bid. Concrete supply, scheduled at 7 months
was delivered on time, allowing the project to go on to a timely completion.
